Patent ES-442609-A1 (ES)
Title: Method for providing electrical isolating material in selected regions of a semiconductive material and the product produced thereby
IPC: H01L21/74
Filed: 1975-11-14
Abstract: An integrated circuit having dielectric isolation is fabricated by growing a double epitaxial layer of N-type semiconductive material onto a P-type substrate. A dielectric layer is formed over the epitaxial layer and thereafter the dielectric and the epitaxial growth are removed in selected isolation regions to expose the substrate. A metal layer is evaporated onto the device so that metal is deposited both on the exposed substrate material and on the dielectric layer. A dielectric is formed by selectively anodizing the metal deposited on the exposed substrate to provide electrical isolation between the remaining portions of the epitaxial growth. Because of the electrical insulating characteristics of the dielectric layer, the metal deposited on the dielectric layer is not anodized and may be removed using a compound that attacks the unanodized metal and has little effect on the anodized metal. Base and emitter elements are formed in the conventional manner to complete the integrated circuit.

Title: Fiber optic transmission line
IPC: G02B6/44
Filed: 1976-02-13
Abstract: A fiber optic transmission line suitable for use in a submarine cable wherein one or more helically formed optical fibers are positioned lengthwise within a flexible tubular member containing a semi-fluid gelantinous substance.

Title: Froth flotation apparatus and method.
IPC: B03D1/14
Filed: 1983-04-11
Abstract: A froth flotation apparatus for elimination of solid particle impurities contained within a liquid includes a vessel defining a flotation cell which includes an upstanding foam discharge conduit, an inlet conduit communicating with the vessel such that fluid flowing through the inlet conduit and into the vessel moves in a vortical fashion within the vessel, a skimmer, and a sparger. The skimmer consists of a generally cylindrical roller which is rotatably mounted between the discharge conduit and a side wall of the vessel and is buoyant so that it floats on the surface of the fluid within the vessel such that it is rotated by the vortical movement of the fluid within the vessel to prevent buildup of foam and maintain the motion of the fluid within the vessel. The sparger includes a substantially cylindrical porous element mounted on a tubular shaft which is rotatably mounted within the inlet conduit and driven by a motor. Compressed air is forced through the porous element to aerate the fluid entering the vessel. Two or more flotation cells may be arranged in a tower to provide series operation in which the liquid effluent of one cell flows downwardly by gravity into a subsequent cell, thereby eliminating the need for additional mechanical pumps.

Patent ES-8402211-A1 (ES)
Title: Pressure regulating valve for a hydraulic vehicle brake installation.
IPC: B60T8/26
Filed: 1983-05-10
Abstract: The invention relates to a pressure regulating valve for an hydraulic vehicle braking system, comprising a housing which has a main cylinder connection and an inlet chamber connected therewith, as well as a wheel cylinder connection and an outlet chamber connected therewith. A piston is arranged between the two chambers and normally leaves open a connection between them. A valve member is adapted to be moved when a certain deceleration force acting upon it is exceeded into a closed position in which it interrupts the connection between the two chambers. Thereupon, when pressure in the inlet chamber continues to increase, the piston enlarges said inlet chamber at the expense of the outlet chamber. A throttle member is arranged in the outlet chamber and normally leaves open the wheel cylinder connection but is adapted to be moved by the flowing brake fluid on sudden brake actuation into a position in which it partially covers the wheel cylinder connection. In this way, when the brake fluid flows too rapidly on sudden actuation of the main cylinder, the brake fluid itself causes its own path to the wheel cylinder connection to be partially blocked, thus preventing an excessively abrupt pressure increase in the-or each of the-connected wheel cylinders.

Patent ES-8503784-A1 (ES)
Title: Electronic control system for a fuel pump
IPC: F02D41/22
Filed: 1984-04-18
Abstract: An electronic control system for a fuel pump of an internal combustion engine includes a power circuit which controls the flow of electric current in an electromagnetic device coupled to a spill valve of the fuel pump. Power is supplied to the power circuit through a resistor through which power is also supplied to an engine speed sensing circuit. The system also includes a control unit which supplies control signals to the power circuit to effect closure of the valve and hence delivery of fuel, in timed relationship with the engine. The control unit receives the speed signal from the speed sensing circuit and also senses the voltage applied thereto. In addition it receives a demand signal from a transducer and controls current flow in a relay winding having contacts in parallel with the resistor. In normal operation the contacts are closed but in a fault situation with the demand low and the speed high the winding is de-energized and the voltage applied to the power circuit and speed sensing circuit falls below a standby level which is sensed by the control unit to maintain the winding energized.
